  • Patent number: 11415837
    Abstract: The present disclosure relates to a display panel, a manufacturing method thereof and a display device, in the field of display technology. The display panel comprises a first substrate; a second substrate, opposite to the first substrate; and a sealant, between the first substrate and the second substrate; wherein a first super-hydrophobic layer is between the first substrate and the sealant; and the first super-hydrophobic layer is formed by a reaction between photopolymerizable monomer and siloxane having a reactive double bond under light. The arrangement of the super-hydrophobic layer can effectively prevent moisture from entering the display panel. Thus, the waterproof performance of the display panel is improved and the display panel can still function normally when it is in a high temperature and high humidity environment for a long time.

  • Patent number: 9074044
    Abstract: Polyether polyols having equivalent weights of up to 500 are continuously prepared in the presence of a double metal cyanide catalyst. A first step of the reaction is performed at a temperature of at least 150° C., while controlling the hydroxyl content and unreacted alkylene oxide content of the reaction mixture to within certain ranges. A portion of that reaction mixture is withdrawn and permitted to react non-isothermally to consume the unreacted alkylene oxide. This process is highly efficient, does not result in catalyst deactivation, as is commonly seen in previous processes, and does not produce a significant ultra high molecular weight tail.

  • Publication number: 20120325737
    Abstract: A polymer or polymer composite membrane having through-thickness micropores and a method of preparing the same are provided. More particularly, a polymer or polymer composite membrane having a pore structure such that micropores are aligned in a mesh structure in the thickness direction of the polymer or polymer composite membrane due to unidirectional freezing in the thickness direction of a solvent. The membrane has through-thickness micropores, and thus has improved permeability in the thickness direction and superior uniformity in size of the micropores and wall thickness between the micropores. For these reasons, the membrane can be used for a porous membrane substrate, microfiltration membrane, etc.
